My brother bought himself a new Core i7 rig, and his old Athlon64 setup turned into an attempt at a HTPC. We threw in an MSI GeForce 9400GT, installed Ubuntu, added the XBMC ppa, then set about trying to make it work with the TV.
The TV in question is a Panasonic TH-42PX80U. The plan was to hook up via HDMI. We set the computer up with a normal VGA monitor and the HDMI connection, logged into Gnome, ran "gksudo nvidia-settings" and tried to make it work. nvidia-setting saw the TV, and, near as I can tell, properly identified it. However, no matter how I tried to configure it (TwinView [clone, left of, right of] or Separate X Screen), I couldn't get a usable signal.
This was with the Ubuntu-supplied 180-series drivers. Thinking maybe it was a driver issue, I uninstalled all things "nvidia" on it, downloaded the 185-series drivers from Nvidia, and tried those. Same result.
Thinking it was maybe an Ubuntu issue, I grabbed my openSUSE rig. That has the very same GeForce card in it as the HTPC. I use an Insignia LCD HDTV connected via HDMI for my monitor. I log into KDE 3.5, run "kdesu nvidia-settings" and try and get it going. Same thing - it sees the TV, everything looks like it's configured properly, but no usuable signal.
In any of the three configurations, I occasionally get something to output on the TV. More often than not, I get snowy static on X start-up. Every once in a while, I get full-height, maybe-one-sixth width picture of what should be displayed (seems to only happen with the screen saver).
Any ideas? I'm kind of at a loss as to why it's not working. Since my brother's Xbox360 crapped out the other day (RROD), we'd very much like to have our media box play stuff on the big screen. Thanks.
